New details have surfaced showing off what the 2015 version of Dell's XPS 15 line may be packing when it makes its debut. According to the report, which is very similar to what was reported late last week, there will be two versions of the computer, both of which will feature a new Infinity Edge touch screen that is said to have a resolution of 3840x2160 pixels and will be produced by Sharp. The computer will also come in a 1080p non-touch variant at a later date.
